Deletion does not cancel any repairs or Apple Store orders. However, any appointments you have scheduled at the Apple Store will be canceled and any open Apple Care cases will be permanently closed and unavailable once your account is deleted.

Deactivation does not cancel any repairs or Apple Store orders. Any Apple Care cases in progress will be preserved while the account is deactivated but you will not be able to access them. Any appointments you have scheduled at the Apple Store will be canceled.
